Does the graph represent a function?

Answer:

Step-by-step explanation:

Given

Points: (0,3) and (-4,-1)

Formula

x = 0 to find the y intercept

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = - 1

x2 = 0

x1 = - 4

m = (3 - -1)/(0 - - 4)

m = 4/4

m = 1

You have y = mx + b so m = 1

the general equation becomes y = x + b

Use point (0,-4)

y = x + b

- 4 = 0 + b

b = - 4

y = x - 4

Answer:

1275

Step-by-step explanation:Step-by-step explanation:

For us to get the Simple interest, we have to use the formula:

= PRT

= Principal × Rate × Time

= $8500 × 5% × 3

= $8500 × 5/100 × 3

= $8500 × 0.05 × 3

= $1275

Answer:

Perimeter of i - 22CM

Area of i - 13CM^2

Perimeter of ii -38CM

Area of ii -66CM^2

Perimeter of iii -30CM

Area of iii- 42CM^2

Perimeter of iv - 50CM

Area of iv- 126CM^2

Step-by-step explanation:

SHAPE I:

PERIMETER = S + S + S + S + S +S

= 7 + 1 + 5 +3 +4 +2

= 22CM

AREA = Part a - 4 * 2 = 8cm^2 part B - 5 *1 = 5cm^2

Total = 8 + 5 = 13cm^2

SHAPE II:

PERIMETER = S + S + S + S + S +S

= 4 + 4 +5 + 6 + 9 + 10

= 38 CM

AREA = Part a - 5 * 10 = 50 cm^2 part B - 4 *4 =16 cm^2

Total = 50+16 =66 cm^2

SHAPE III:

PERIMETER = S + S + S + S + S +S

= 9 + 2 + 3 + 4 + 6 + 6

= 30CM

AREA = Part a - 6 * 6 = 42cm^2 part B - 3 * 2= 6cm^2

Total = 36 + 6 =42 cm^2

SHAPE IV:

PERIMETER = S + S + S + S + S +S

= 9 + 10 + 4 + 6 + 6 + 15

= 50 CM

AREA = Part a -15 * 6 = 90 cm^2 part B - 9 *4 = 36cm^2

Total = 90 + 36 = 126cm^2

Answer:

4, 8 and 16

Step-by-step explanation:

a/r ×a×ar =512

a^3 =512

a = cube root of 512

a=8

8/r+8+8r=28

8r^2+8=20r

8r^2-20r+8=0

8r^2-16r-4r+8=0

8r(r-2)-4(r-2)=0

(8r-4)(r-2)=0

r=2

8r=4

so r=2 or r=1/2

so of r is 2

8/2=4

and 8×2=16

Answer:

[tex]y = - 4x - 1[/tex]

Step-by-step explanation:

The standard equation for slope intercept form is

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

plug -4 as m and -1 as the y intercept

[tex]y = - 4x - 1[/tex]

Answer:

$14

Step-by-step explanation:

Let x = number of subscriptions sold

Total income of Ayana per hour = $12 + $1x

Total income of Victor per hour = $6 + $4x

To find the number of subscriptions that would equate their incomes :

$12 + $1x = $6 + $4x

Collect like terms

$12 - $6 = $4x  - $1x

$6 = $3x

Solve for x

x = $2

The subscription that would equate their income would be $2.

The income each would earn = $12 + $1(2) = $14

Answer:

Inequality

Step-by-step explanation:

There are an infinite number of quantities less than 6 (5, 4, 3, 2, 1, 0, -1, -2, -3...) so it is much easier to write an inequality

Answer:

x = -8

Step-by-step explanation:

-2.5x - 2 = 18.

Add 2 to both sides.

-2.5x = 20.

Divide both sides by -2.5.

x = -8

Answer:

the  money spend on tomatoes is $4.20

Step-by-step explanation:

The computation of the money spend on tomatoes is shown below

Let the money spend on tomatoes be x

So

[tex]2 \frac{3}{4} \times \$1.32 + 1\frac{1}{2} \times \$1.20 + x = \$9.63\\\\[/tex]

$3.63 + $1.80  + x = $9.63

x = $9.63 - $3.63 + $1.80

= $4.20

Hence, the  money spend on tomatoes is $4.20

Answer:

B, 82 meters cubed

Step-by-step explanation:

The formula for volume of a triangular pyramid is 1/3Ah, where A = the area of the triangular base, and h = the height of the pyramid.

The area of the base here is 1/2 base x height, so:

1/2 x 8.2 x 4 = 1/2 (32.8) = 16.4 meters squared.

Plug this into the formula for the volume of the pyramid:

1/3 x 16.4 meters squares x 15 meters = 82 meters cubed
